Here is one modification that I found that will convert your ICOM IC-3200A
for operation on the 430-440Mhz band.
This is a very simple modification and does nothing to harm the radio,
no trace cuts, changing IC's or any of those problems.
The only minor problem is that you lose all your memories when it is
first done, so if you need to, wrtie those 2 meter assignments for re-entry
afterwards. Since the radio will only operate on the 430-440Mhz portion of
the UHF spectrum afterwards use on 440-450Mhz can only be done only after
the modification is cancelled.

Just inside the front panel of the ICOM IC3200A on the top there is a
circuit board that can be seen with the top cover of the radio removed.
There are several componets that can be viewed from this angle, look for
a jumper marked "J-8", this is for reference only.


To the side of this jumper, towards the small ribbon cable going to the
display there is another jumper labled "J-10", this is next to the
Capacitor labeled "C-4", also in this neighborhood is a mounting screw
(just for reference).   The only "mod" that you need to make is to lift
the jumper "J-10" for a few minutes and re-install the jumper back in the
same location that it was removed from - THAT is all!

To un-do your "mod" turn off the radio and at the same time depress the
"function" button and indicated in the owners manual and normal operation
of the ICOM IC-3200A is resumed.

I have verified the frequency and sensitivity of the radio after the "mod"
was completed and the frequency display is accurate but the sensitivity at
the lowest portion of the band on my '3200 was a bit deaf, with proper
tuning of the VCO would certainly allow better preformance.


Anyone with other "mods" for this radio?
I'm still looking for the same type of "mod" for use with my
ICOM IC-471H if anyone knows of one.
